common problems are

1. date formats

2. handling table control in BDC's

3.not passing the essential data

4.selecting the suitable method for data migration

5.not calling the fm BAPI_TRANSACTION_COMMIT after calling the suitable BAPI

Common problem in case of BDC is change of sequence in screens due to which screen number changes.

Also, the file layout. If there is a change in the file layout it must be notified to all concern groups who receive this layout.

Hi Chandana,

sorry to answer u asked skj....

k let me tell you the problems what ever i faced while uploading

1. Screen sequence may mismatch means like u do recording giving some values in the fields and if atleast one field in the flat file mismatches then after that every field goes wrong.

2. Data types mismatch: like if you specify the date format like ddmmyyyy and if the flat file contains mmddyyyy then u may get such type of errors

3. some more common BDC errors are ( Data for Screen Not Found, Field Not available in Screen ). These again are transaction specific and you have to analyze it by calling the transacion in display ALL mode.

4.Authorization problems.

5. intermediate screens missing like pop up screens.

6. In lsmw specifically i can say field mapping is the crucial point, if you don't do it properly then everything goes wrong...

may be helpful for you.....
