Thanks Muthu,
This is indeed a excellent summary on both.
We completed one way scenario using the BAPI - procord_get_details to read data from ecc to mii and share with MES.
My SAP team however couldnt get find BAPI for reversal scenario - MII to ECC.
To update the confirmed quantity in ECC,which MII has read from MES.
Can you share bapi to update this detail into ECC.also field mapping
like AUFNR - Process Order number
IFTNR - start date and also on....
so that i can mapped exact field data in MII corresponding to BAPI to update/and reflect the change in ECC SAP fields.
Again,thanks a ton for ur detailed reply
