BAPI PO change - Custom fields modification

[itabhishek9]

Hi SDNites,

I have enhanced EKPO table where the table has quantity custom field as well. So when I am using BAPI_PO_CHANGE, it is not allowing me to do due to the quanity fields in enhanced EKPO table.

In order to achieve the above, I am trying to implement method MAP2I_EXTENSIONIN of BADI ME_BAPI_PO_CUST. Can you please help me how do I convert th quantity field in changing structure CH_STRUC. When I am trying to do the same it is giving a short dump. Can you please advise or provide a sample code.

Regards,

Abhi

Did you copy from demo class CL_EXM_IM_ME_BAPI_PO_CUST, also did you read the EXTENSIONIN documentation.

If you "played" with numeric data... then look for class on data container like CL_ABAP_CONTAINER_UTILITIES to map data before extensionin and your structure without raising some exception.

Thanks Ray for your response.

Yes I have copied from class CL_EXM_IM_ME_BAPI_PO_CUST.

Also when I call BAPI_PO_ChANGE, it will internally call the BADI ME_BAPI_PO_CUST and here within method MAP2I_EXTENSIONIN we get startucture CH_STRUC already populated with EKPO custom fields but without values. Here I have to change the structure itself so that it can hold CHAR values.  Can you please suggest. (I feel CL_ABAP_CONTAINER_UTILITIES can convert the values and not the structure).

We had a similar requirement to change the value of a Z field added in EKPO table through BAPI_PO_CHANGE.

Here's a code snippet

DATA: ls_extensionin type bapiparex,

            ls_ext_po type bapi_te_mepoitem,

            ls_ext_pox type bapi_te_mepoitemx

IF wa-zzdel is not initial.

ls_extensionin-structure = 'BAPI_TE_MEPOITEM'.

ls_ext_po-po_item = ebelp

ls_ext_po-zzdel = zzdel

ls_extensionin+30(960) = ls_ext_po.

append ls_extensionin to lt_extensionin.

ENDIF.

Repeat the same 5lines also for 'BAPI_TE_MEPOITEMX'  but pass zzdel flag as 'X' and the next structure would be ls_ext_pox for flags.Rest all remains same.

So you would have 2entries in your lt_extensionin structure.One with values and one with flags.

Pass the table in BAPI.Your Z fields would be updated .

Thanks Ruchi.

As i mentioned the EKPO custom fields has quantity field due to which I have to convert it to Char before calling BAPI_PO_CHANGE which I have done it.

Within BAPI, the BADI has to be called as enhanced EKPO structure is having quantity field. I am looking after what needs to be written in this BADI to do the necessary structure conversion.

If you have any other approach please let me know.
