ALE IT0105 idoc update problem

[Former Member]

Hi all.

I have created Idoc type HRMD_A with 0105 infotype (communication) sending from target to source system. Also I`ve set change pointers for this message type. In case of sending idoc with new username record everything works correct. But when i try to change existing field in IT0105 using tcode PA30, target system receives updated Idoc with status 51, message "You cannot update infotype 0105 on database table PA0105 (Check the entries in table T777D and restart inbound processing)". Updates of other infotypes work correct.

I`ve checked table T777D and have not find any problems. I`ve looked up and read all related topics is SAP Forum (for example, ), checked all suggesting steps, but it didn`t help to solve problem.

Please, help me.

Did you check T777D for IT0105 on the receving system to see if it's the same as in sending system ? Also, if you have PA30 access in receiving system (test or prod), just try to go in an existing IT015 and change to see what message you'll get if any .

Hi, Ted.

Thanks for your answer. Records for IT0105 in source and target tables T777D are identical. When I try to change uname in PA30 manually, no error is executed.

Any other suggestions?

Did you create an IT0105 with a newer date, or override existing IT0105 with differerent user id ? Also, what is the message id/ number in the inbound idoc message ?
