Hi all,

Is there any user exit which consists of EKKO structure as CHANGING or TABLES parameter. My requirement is when the user press save while creating STO i have to do some validations and keep the document under hold. For this in EKKO table there is one flag indicator called <b>MEMORY</b> field. this field will be BLANK if the document is to be saved and it will be 'X' if the document is to be kept under HOLD. Please also let me know if any other structre has this field or any other field which indicates HOLD/SAVE status.

Thanks in Advance,

Hi Vinod..

You can implement the BADI named ME_HOLD_PO (Check in Tcode SE18)

It has the method IS_ALLOWED in which there is PARAMETER called IM_EKKO .

see the Documentation of this BADI in SE18

and implement it in SE19.

reward if Helpful.
