Using a cursor created with SELECT statement as RecordSource of a grid is not advisable. Make use of a Cursor created with CREATE CURSOR and populate it the way you want. Everytime you need new contents of the cursor, ZAP it and populate it again.

>I have a form with a combo box that selects code numbers from Products table; I have a grid that displays inventory transactions of the product chosen in the combo box. I have this code in the InteractiveChange event of the Cbox:
>
>PUBLIC varCodigo
>RELEASE ALL
>varCodigo=THIS.VALUE
>SELECT PRODUCT
>LOCATE ALL FOR codigonues=THIS.VALUE
>THISFORM.REFRESH
>DO invent
>
>Invent is a program that runs and adds transactions to the child table, based on the Code number selected in the combo box. Everything works fine except that when I try to END TRANSACTION, my grid goes blank, although the record is correctly added.
>
>I have this line of code in certain point of the invent program:
>
>SELECT MAX(Nivel) AS MaxLevelNo FROM invent WHERE codigonues = varCodigo INTO CURSOR myCurs
>
>The grid displayed correctly the new record BEFORE I added this line.
>
>Now it goes blank and even worse, the combo box can not filter the records anymore.
>
>I hope this is clear and somebody can help
