field module on request in Module pool

Former Member — Tue, 04 Oct 2011 16:42:19 GMT

Hi All,

I am trying to call a z transaction through BDC. but I am stuck due to

*field <screen-field>*

*module <name of the module> on request.*

In the above module some internal tables are getting cleared so my BDC is erroring out.

when I run the transaction directly above statements are not triggering and when I run my BDC these statements are triggering.

Can some body please let me know how I can handle not to trigger above statements..??

Thanks,

Rajesh

Hi,

I believe your BDCDATA has some value or overwrites an existing value with initial value.

The module <mod> is only called if the user has entered something in the field. This includes cases when the user overwrites an existing value with the same value, or explicitly enters the initial value.

check this [documentation|http://help.sap.com/saphelp_46c/helpdata/en/9f/dbabbd35c111d1829f0000e829fbfe/content.htm]
