How to initialize internal table with array of strings using 'value' operator in ABAP?

[former_member763677]

Hello Folks,

I am trying the below code to set up array of strings in internal table.

types: tt_input type standard table of string with default key.

data(gt_input) = value tt_input( ( 'string1' ) ( 'string2' ) ).

But it shows syntax error '"string1'" and the row type of "GT_INPUT" are incompatible.'

When I try to set array of integers I face no proplem.

types: tt_input type standard table of i with default key.

data(gt_input) = value tt_input( ( 1 ) ( 2 ) ).

Any thoughts please ?

types: tt_input type standard table of string with default key.
data(gt_input) = value tt_input( ( `string1` ) ( `string2` ) ).

to generate string use ` not ' (it will generate char)

Is there a way to have the mix of both integer and string ?

[FredericGirod]

Sorry, what do you mean ? having integer in the string ? or generate a type from the data you receive ... ?

[former_member763677]

something like this [ `string1`,`string2`,100,200,'string3` ] , having an array of integers and strings in the same internal table. is it possible ?

if we have a way to generate type from the data we receive that would be great to know too.

types: tt_input type standard table of string with default key.

data(gt_input) = value tt_input( ( `string1` ) ( `string2` ) ( conv #( 100.00 ) ( |{ my_integer }| ) ).

the dynamic generation is not an easy task. the key words are RTTS
