Hi,

You can get some of the following errors..

1, First one may be data mismatching of fields.

2. Value range may be different for some material and customer number etc,,

3. Some of the combination of the fields may not match like sales area..(Sales Org, Distribution Channel and Division)

4, Contry codes may be different

5. Data type may mis match and length of the fields may be different..

6. Mostly the validations of the fields will give errors.

So better to validate the data in the flat file and then pass those values to the BDC data would be best practice.

Whether its a back ground or on line you have to handle the errors explicily in Call Transaction method and for Session methed the system will generate error log.

Hi Reema,

As of your question, there may be several reasons for failure of the bdc.

I will explain you , with an example.

As we know, errors in Call transaction are captured through table via a structure called BDCMSGCOLL.

It display, the field name, screen name, screen number and message type..so on.

For instance, if you have coded that, through bdc, the value of MEINS is filled up. But, if there is no value in the incoming file or text file. then in foreground it won't show's an error, when you run it in back ground, it triggers an error.

This is what practically i have faced.

Like few reasons

1. Date format

2. Currency not assigned correctly.

3. even some errors for back ground might be session not closed .

Thanks
