Delta is failing from last 5 days...........................

Question

Error Message: When u go into the "Maintain Variant" you get a pop up showing the following message -
Delta request REQU_45994EYUQ7MJ7OCY06G5HQS6N is incorrect in the monitor
A repeat needs to be requested
Data target YGTDS_C01 still includes delta request REQU_45994EYUQ7MJ7OCY06G5HQS6N
Data target YGTGD038 still includes delta request REQU_45994EYUQ7MJ7OCY06G5HQS6N
If the repeat is now loaded, then after the load
there could be duplicate data in the data targets
Request the repeat?
If you press on "Continue" It will take you to the IP & monitor screen.
If you go to the "Status" Tab the error message is like this :-
No valid assignment from Customer 0000236317 to Channel data incomplete.

Can someone help me in solving the issue.......................

Answer 1

Does your transfer/update rule do something with this "customer" number? A masterdata lookup? ("channel'?) 
It seems like you try to upload data referring to another field which is not filled and therefor he can't update.
