CUO1 - BDC not working in the background.

Hello Experts,

We are trying to create dependencies using CU01, when we recorded through LSMW we have got an error saying *for type c' lenght can be from 1 to 65535, ( * caution message arised in the field mapping step)*

we went on with a work around with a BDC, while recording we didn't find any errors,also when processing the recording the system doesn't throw any status message.

After creating a ABAP program with the recording, we are seeing the status message when we run them in the "A" all screen mode when we press enter it is able to create the dependency however the BDC is not able to run in the background throwing with the same status message ($ it is not a screen field).

thanks
