Hi Frederic,
By Default System message will include Member ID information in the process log. Because any member description is retrived thru Memmber ID only. This is new to me that. ID is dis-appearing.
Have a check.
1. Go to the back end(Tx-RSA1) - Model and see the content with Member id & Description.
2. May be when you submited the data from "Input schedule you forget to key in the ID?
Hint: When you submit the records from -Input schedule. Do you get the message. That "X " No-of records are submited. If you are get this message. The input schedule is doing good.
Give a test. Enter one ID + Description and click the submit. Then you should get 1- records submitted.
Hope this helps-Thank you.
