Momwe mungaphatikizire chithandizo cha ogulitsa awiri pa SAP mu maola 12

Nkhaniyi ikuuzani za ntchito yayikulu yoyendetsera SAP mu kampani yathu. Pambuyo pa kuphatikizika kwa makampani a M.Video ndi Eldorado, madipatimenti aukadaulo adapatsidwa ntchito yosakhala yaing'ono - kusamutsa njira zamabizinesi kupita ku backend imodzi yozikidwa pa SAP.

Tisanayambe, tinali ndi zida zofananira za IT zamaketani awiri ogulitsa, okhala ndi malo ogulitsa 955, antchito 30 ndi ma risiti mazana atatu patsiku.

Tsopano popeza zonse zikuyenda bwino, tikufuna kugawana nawo nkhani ya momwe tinatha kumaliza ntchitoyi.

M'bukuli (woyamba mwa awiri, omwe akudziwa, mwinamwake atatu) tidzakupatsani inu zambiri za ntchito yomwe inachitika, zambiri zomwe mungapeze pa msonkhano wa SAP ME ku Moscow.

Miyezi isanu ndi umodzi yopangira, miyezi isanu ndi umodzi yolemba, miyezi isanu ndi umodzi yakukhathamiritsa komanso kuyesa. NDI Maola 12kuyambitsa dongosolo lonse m'masitolo 1 ku Russia (kuchokera ku Vladivostok kupita ku Kaliningrad).

Zingamveke ngati zosatheka, koma tachita! Tsatanetsatane pansi pa odulidwa.

Pophatikiza makampani a M.Video ndi Eldorado, tidayang'anizana ndi ntchito yokonza ndalama ndikuchepetsa njira zamabizinesi amakampani awiri osiyanasiyana kumbuyo imodzi.

Mwina izi zitha kutchedwa mwayi kapena mwangozi - ogulitsa onse adagwiritsa ntchito machitidwe a SAP kukonza njira. Tidayenera kuthana ndi kukhathamiritsa kokha, osati kukonzanso kwathunthu kwamkati mwa netiweki ya Eldorado.

Kugwira ntchito, ntchitoyi idagawidwa m'magawo atatu (kwenikweni anayi):

1. Kupanga "papepala" ndi kuvomereza akatswiri athu amalonda ndi alangizi a SAP kwa njira zatsopano (komanso zamakono zamakono) mkati mwa machitidwe omwe alipo.

   Pambuyo pofufuza zizindikiro zingapo za backend yomwe ikugwira ntchito kale ya makampani awiriwa, M.Video backend inatengedwa ngati maziko a chitukuko cha dongosolo logwirizana. Chimodzi mwazinthu zazikulu zomwe chisankhocho chidapangidwa chinali kuchita bwino kwa kampani yonse, ndalama zambiri komanso phindu pamitengo yotsika yamabizinesi.

   Kusanthula ndi kupanga gawo linatenga pafupifupi miyezi isanu ndi umodzi, mabiliyoni a maselo a mitsempha kuchokera kwa akuluakulu a dipatimenti ndi akatswiri aukadaulo, ndipo malita ambiri a khofi anali ataledzera.

2. Kukonzekera mu code. Nazi manambala kutengera zotsatira za polojekiti:
   • Njira zokwana 2 patsiku zokonzedwa pogwiritsa ntchito gawo lothandizira.
   • Ogwiritsa ntchito 38 kutsogolo ndi kumbuyo.
   • 270 katundu m'malo osungiramo mabizinesi ophatikizidwa.

   Pafupifupi macheke a 300 omwe amakonzedwa ndi makinawa patsiku, omwe amasungidwa mpaka zaka zisanu kuti apatse makasitomala chitsimikizo, komanso pofuna kufufuza msika.

   Kuwerengera malipiro, zopititsa patsogolo ndi mabonasi a antchito 30 mwezi uliwonse.

   Ntchitoyi inaphatikizapo gulu la akatswiri 300 aluso omwe anagwira ntchito kwa miyezi khumi. Pogwiritsa ntchito masamu owerengeka osavuta, timapeza ziwerengero ziwiri zomwe zikuwonetseratu kukula kwa ntchito yomwe yachitika: 90 anthu/masiku ndi… 000 maola ogwira ntchito.

   
   
   Chotsatira - kukhathamiritsa kwa machitidwe amtundu wa SAP; pafupifupi machitidwe zana adafulumizitsidwa kasanu mpaka kasanu ndi kamodzi pakukonza ma code ndi mafunso mu database.

   Muzochitika payekha, tinatha kuchepetsa nthawi yochitira pulojekiti kuchokera ku maola asanu ndi limodzi mpaka mphindi khumi mwa kukonzanso mafunso ku DBMS.

3. Gawo lachitatu ndilovuta kwambiri - kuyesa. Zinali zozungulira zingapo. Kuti tichite izi, tidasonkhanitsa gulu la antchito 200, adagwira nawo ntchito, kuphatikiza ndi kuyesa kuyambiranso.

   Tidzafotokozera zoyezetsa katundu mundime yosiyana; iwo anali ndi mikombero ya 15 pagawo lililonse la SAP: ERP, POS, DM, PI.

   Kutengera zotsatira za mayeso aliwonse, ma code ndi magawo a DBMS, komanso ma index a database adakonzedwa (timayendetsa pa SAP HANA, ena pa Oracle).

   Pambuyo pa mayesero onse olemetsa, pafupifupi 20% yowonjezera inawonjezeredwa ku mphamvu yowerengera makompyuta, ndipo nkhokwe ya voliyumu yofanana (20%) inapangidwa.
   Kuphatikiza apo, titachita zozungulira zomwe tafotokozazi, tidayamba kusanthula mapulogalamu 100 omwe amagwiritsa ntchito kwambiri zida, kutengera zotsatira zomwe tidasinthanso kachidindo ndikufulumizitsa ntchito yawo pafupifupi kasanu (zomwe zimatsimikiziranso kufunikira kwa refactoring ndi kukhathamiritsa ma code).

   Kuyesedwa komaliza kunali "kudula". Malo osiyana oyesera adapangidwira, omwe adatengera malo athu opangira deta. "Tidadulira" kawiri, nthawi iliyonse pamatenga pafupifupi milungu iwiri, pomwe tidayesa kuthamanga kwa ntchito monga: kusamutsa makonda a pulogalamu kuchokera kumalo oyesera kupita kumalo opangira, kuyika malo otseguka azinthu zosungira katundu ndi nthawi zosapezeka. ntchito.

4. Ndipo gawo lachinayi - kuyambitsa mwachindunji atapambana mayeso. Ntchitoyi inali, kunena zoona, yovuta: mu maola 12 kusintha masitolo pafupifupi 955 m'dziko lonselo, ndipo nthawi yomweyo osasiya malonda.

Usiku wa February 24-25, gulu la akatswiri khumi a kampani yathu linatenga "kuyang'ana" mu data center, ndipo matsenga a kusinthako anayamba. Tidzakambirana mwatsatanetsatane pamsonkhano wathu, ndiyeno tidzapereka nkhani yachiwiri kuzinthu zamakono zamatsenga athu a SAP.

Zotsatira.

Kotero, zotsatira za ntchitoyo zinali kuwonjezeka kwa zizindikiro monga:

• Katundu pa backend pafupifupi kawiri.
• Chiwerengero cha macheke patsiku chinawonjezeka ndi 50% kuchokera ku 200 mpaka 300 zikwi.
• Chiwerengero cha owerenga frontend chinawonjezeka kuchokera 10 zikwi 20 zikwi.
• Mu gawo lowerengera malipiro, kuchuluka kwa ogwira ntchito kudakwera kuchokera pa 15 mpaka 30.

Tidzakambirana zambiri zaukadaulo pamisonkhano yathu ya SAP ku Moscow, yomwe idzachitika pa June 6 ku ofesi ya M.Video-Eldorado. Akatswiri adzagawana zomwe adakumana nazo pakukhazikitsa. Kutengera zotsatira za msonkhano, akatswiri achinyamata adzatha kupeza internship malipiro pa kampani ndi chiyembekezo ntchito zina.

Mutha kudziwa zambiri ndikulembetsa pa izi
