Hi Arman,
Totally you are updating 30 records via BDC, kindly check the following.
- Check Whether the problem occurring for only 22 nd record or for all the records after 22 nd. To find out Update the last 10 records in the system separately instead of updating everything.
The field doesn't exist problem commonly raise, when there is a condition based screen element is hidden. During BDC recording, we will consider these problems and all. For those type cases only we always prefer BAPI instead of BDC.
Kindly check using MODE 'A' in CALL Transaction statement, that helps to find the problem in foreground.
