We performed the support pack upgrade on both R/3 4.6c and SCM 4.0 on the March 23 of this year. Our APO business analysts approved that everything works fine. But today, they found that the Materials are not getting transferred from SCM to R/3. I am a basis person. I am trying my best to reproduce what was explained to me.
They run a Demand Planning background job twice a month that transfers materials from SCM to R/3. The name of the job is 'ZMRP_RELSE'. And I believe this job is associated to an activity and the name of the activity is 'ZMRPREL_R3'.
When they run the job in the SCM box, the runs successfully and it says 'X' number of materials transferred. But, when the business analysts go to the R/3 box and check the status in the transaction 'MD63', it says the last successful transfer happened on March 9, 2007.
I tested everything from my end - background workprocess, RFC connections, etc. I am not sure how exactly to proceed about this. It would be really helpful if someone can guide me through this solving this problem.
