Select Options Problem

Hello All,

I'm facing a strange issue regarding select-options.

Initially I was using like this,

MOVE: 'I' TO r_wildcard-sign,

'EQ' TO r_wildcard-option,

'++++++++++B' TO r_wildcard-low.

APPEND r_wildcard.

SELECT * FROM mara

INTO TABLE gt_mara_b

WHERE mtart = 'YSAB'

AND matnr IN r_wildcard.

This range in the select query fetched many records.

But now the above query is not working and it is giving null records. So I changed the condition in the

select-options as 'CP' instead of 'EQ', now the select query is fetching more records as before.

Could anybody tell me why this behaves like this.

Perfect solution is highly appreciated.

Regards,
