Normally you can not filter on a memo field in Crystal Reports. But there is a workaround.
- Create a parameter parFILTER, type STRING
- Create a Formula Field and call it frmFILTER
- In that Formula Field put a formula like this:
- Then filter on this Formula Field
- Pick: IS TRUE
The memo field now will be filterd by the text given in the parameter parFILTER.
