How to obtain list of values of second field based on the selected entry of first field.

Hi,

I have a search help with two fields , each having a search help enabled.

First, I press F4 on first field and select a record from it. Then, I press F4 on the second field, I need to get only those data  based on the first field value.

I am using a Search help exit instead of the program, as I need to attach this search help on ME23N transaction, Internal order number data element AUFNR.

Once I select a value from the hitlist provided by the first field, is it possible to capture the selected record ?

I saw in the forum , that we can use RETURN step (similar to PRESEL, SELECT or DISP) of the Search help exit.

How can we trigger the RETURN event and capture the value of the first record, after we have selected from the hitlist ?

Anyone has done it before ?

I believe once I have the value of the selected record, I can pass it to the second field through Shared Memory .

Please provide me with your inputs.

Regards,

Shail.
