Handle back button in standard tcode .

[Former Member]

I am doing a BDC on standard tcode MEMASSPO which displays the 3rd screen directly of the tcode.

Now problem is when I press the BACK button on this screen it takes me to the previous screen of the same tcode.

My requirement is that it should take me to SAP Menu when i click the BACK button.

I am pasting the BDC code below:

START-OF-SELECTION.

PERFORM bdc_dynpro USING 'SAPMMSDL' '0200'.

PERFORM bdc_field USING 'BDC_CURSOR'

'MASSSCREEN-VARNAME'.

PERFORM bdc_field USING 'BDC_OKCODE'

'=TAB2'.

PERFORM bdc_dynpro USING 'SAPMMSDL' '0200'.

PERFORM bdc_field USING 'BDC_CURSOR'

'MASSSCREEN-VARNAME'.

PERFORM bdc_field USING 'BDC_OKCODE'

'=FIND'.

PERFORM bdc_dynpro USING 'SAPLSPO4' '0300'.

PERFORM bdc_field USING 'BDC_CURSOR'

'SVALD-VALUE(01)'.

PERFORM bdc_field USING 'BDC_OKCODE'

'=FURT'.

PERFORM bdc_field USING 'SVALD-VALUE(01)'

'ELIKZ'.

PERFORM bdc_dynpro USING 'SAPMMSDL' '0200'.

PERFORM bdc_field USING 'BDC_OKCODE'

'=NEXT'.

PERFORM bdc_field USING 'BDC_CURSOR'

'MASSFVIEW-FIELDTEXT(02)'.

PERFORM bdc_field USING 'MASSFVIEW-CHECKBOX(01)'

'X'.

PERFORM bdc_field USING 'MASSFVIEW-CHECKBOX(02)'

'X'.

PERFORM bdc_dynpro USING 'SAPLMSMT' '0200'.

PERFORM bdc_field USING 'BDC_CURSOR'

'NONEXT'.

PERFORM bdc_field USING 'BDC_OKCODE'

'=OK'.

PERFORM bdc_dynpro USING 'SAPLMASS_SEL_DIALOG' '0100'.

CALL TRANSACTION 'MEMASSPO' USING bdcdata MODE 'E'.

Please help me.......

Hi

I don't think you can do it, because what the button BACK has to do is in abap code of standard program (in your case MEMASSPO), so you should change it in order to do what you need

Hi,

You can do it by appending (at the end of the BDC data) the exit actions when the screen X (the one you get after the BACK button has been pressed) is reached.

As you run the BDC with mode 'E', it will stop the BDC data when SAP sees that screen X from the BDC data is not the screen currently displayed. Then, if the user displays later the screen X, SAP continues to execute the BDC data from screen X.

This topic is shortly described here: http://wiki.sdn.sap.com/wiki/display/ABAP/BatchInputFAQ#BatchInputFAQ-IsitpossibletosimulateANDSKIPFIRSTSCREENusingBDC%3F

Hi Prabhu. we have the requirement for MEMASSPO as we want to restrict the user to viewing the complete PO.
