I faced the following problem:
"Product does not exist in plant or it has been flagged for deletion". This error message occurs during shopping cart creation or during transferring purchase requisition from R/3 to SRM. It seems like SRM carries out some material checking in R/3 before shopping cart save and can't find out appropriate R/3 material. The only reason I can assume is different material number formats in SRM and R/3. Material number length is the same in both systems.
Thanks in advance,
