Memasspo Issue

Hi Experts,

I have a strange issue and please let us know the reason for the same.

SRM 5.5, ECS Scenario

When I tried to change one of the fields in R/3 PO (Delivery completed Indicator) via MEMASSPO, no issue at R/3 level. However, the same effect will not be available in SRM PO BBP_PDIGP level. I can see the effect in SRM side only on screen level (Process Purchase Order, line item level).

I would like to know the reason for the above action. Why does the system allow to change the ECS PO in R/3 via Memasspo ?

Also why does the system keeping the changes only on screen level in SRM side and not on table level. This will create confusion on Open PO concept.

Thanks

Rajesh K
