Can I INSERT a INITIAL LINE to INDEX 1?

[former_member194142]

Hello

I am writing my code in a user-exit, in this we have a internal table, say sap_itab, but its declared with a DDIC table type, say, DDIC_ITAB, which is a SORTED one, selected the UNIQUE radio button with 3 fields key components.

Now pl. let us know can we INSERT the INITIAL LINE at INDEX 1 to this sap_itab in user-exit? is it safe being a user-exit?

I mean, can we add a INITIAL LINE as INDEX 1 to a SORTED internal table, wherein UNIQUE is se3lcted with 3 fields as KEY COMPONENTS

Pl. check PLM's DDIC TABLE TYPE - 'EHCSMT_SPC_VALIDITY_AREA_DESC'

Thank you

Yes you can. BUT only if there is no entry with a blank key yet and the inserted value does not violate the sort order AND you do not need to change the key values.

If this is safe to do in a user exit is too broad a question, it totally depends on the user exit.

Hi.

Yes, you can (as Gerrit wrote). But I don't think, that this makes any sense in a SORTED table.

Why do you want to do that?

Thank you.

Std. SAP is filling the screen's drop down field with this internal table contents (records), as we knew the std. SAP will add a blank line by default in the drop down field's list box, but for some reason this is not happening (std. SAP's blank line is disappearing) hence user don't have a chance to select NONE/blank line in the drop down field, so we want to add explicitly a blank line to the drop down field's entries, now user can select this blank line as NONE value

Right, I need to investigate/fix 'for some reason', that's we tale care later, right now we need to fix the issue (NONE selection ability) it bcz its a production issue

Thank you

Hi,

Check the field  Attributes-> program (in screen) , if input is selected as required option in list box.

you can't  have blank option in list box.

Hope it helpful,
