Object dependency to read substring

[Former Member]

Hi.

Is it possible to evaluate a substring in an object dependency? I want to write a simple OD that defaults a char field to a month code (the 2 digit month) based on another field which stores a date.

Something similar to this:

$set_default ($self,Z_PUB_MNTH,'01')

    If Z_ON_SALE_DATE+4(2) = '01'                   'date stored as string yyyyddmm

I'm getting these errors:

E28031 Comparison operator required

E28024 Syntax error in simple action/procedure

Any help would be much appreciated. Many thanks.

Hi,

I'm not really used to that syntax but I think this is not possible within an OD...

Can't you use a function module to fetch a char value (with Z_ON_SALE_DATE as input parameter and Z_PUB_MNTH as output)?

Anyway just a guess

Cheers,

Manu.
