Getting the error for COPA

Hello Gurus,

While i m transferring the FERT product with Movement Type 413 via T.Code MB1B, I m entering the receiving and sending plant as required. i have entered all the data. but i m getting warning msg as discripted below.

Sales Order (SOBKZ =) is not provided for this goods movement

Msg No. M7374

Diagnosis:

the special stock indicator for the sales order (VBAP - SOBKZ=) is diff from the special stock indicator in the goods movement

Procedure

Use the sales order that is planned for goods movement.

Now,

that is warning msg so i m ignoring it by pressing Enter

Now I am getting the error msg as below:

Complete PA transfer structure FI

Diagnosis :

Cost Element 41500230 is not assigned to value fields in PA Structure in FI

Earlier i was able to do this transaction smoothly but today i m getting the error like this.

Hope to get back u frnds!!
