Auto populate field 'ABC Indic' under Organization tab in IE01/IE02/IE03

Hi Folks,

I need to Autopopulate the selected value for the 'ABC Indic' dropdown within the 'Location Data' group, under 'Organization' tab in IE01/IE02/IE03, based on a given Business condition for equipment numbers.

The field pertains to ABCKZ of table ILOA (And subsequently in the database view ITOB)

This standard field is made visible in the transactions via configuration.

I understand that I need to make this change using the User exit 'EXIT_SAPLITO0_002'. However, I do not seem to be having a handle to the field ABCKZ as an exporting/changing parameter in any of the exporting structures ISTRU_EQ / ISTRU_EZ / IFLO_USR1). Since this is not a custom field , i am not sure if I must include it as a custom include in one of the afore mentioned structures. ( Even if this were to be done, IFLO_USER1 [which is the exit mod structure for ILOA] does not have a Customer Include)

All I need is a handle to the field, so that i can make the required change and the update will happen without any further interventions.

Any pointers to this issue would be very helpful.

Thanks and Regards,

Puja.
