Query Syntax

Question

Hi Guys,
Is there any where for me to lookup information of syntax that used in queries? I know stored procedure and able to write simply query with no problem
But i encounter a syntax from other partner like:
$[ORDR.DocNum]
$[38.1.0]
/* SELECT FROM [dbo].[OFPR] T0 */
DECLARE @tdocdate as datetime
/* WHERE */
set @tdocdate /* T0.T_RefDate */ = [%1]
this is the syntax i never encounter before... But i know their function. So where can i get more information on this?
Another question:
/* SELECT FROM [dbo].[OFPR] T0 */
DECLARE @tdocdate as datetime
/* WHERE */
set @tdocdate /* T0.T_RefDate */ = [%1]
This prompts the user to enter Posting Date From parameter before query is run. Now, i want to change "Posting Date From" to "Date Start From", how do i do it? And how do i add a new parameter?
I tried to look on SAP but found nothing about this.
I hope u guys can help..
Thanks

Answer 1

alright, at least i got the idea...
so now my requirement is this
/* SELECT FROM [dbo].[OINM] T0 */
DECLARE @fdocdate as datetime
/* WHERE */
set @fdocdate /* T0.Itemcode */ = [%3]
let say this query will bring up a box looks like:
|                                                 |
|   [ ] %0 Item No.        [                   ]  |
|                                                 |
|   [OK]   [Cancel]          [Existing Value]     |
I want it to be become:
|                                                 |
|   [ ] %0 Item No. From   [                   ]  |
|                                                 |
|   [OK]   [Cancel]          [Existing Value]     |
How do i achieve it? I tried this with a user defined field with the name "Item No. From" and it works perfectly. But when i click on "Existing Value", it found nothing since it is not draw from that table..
any idea guys? Thanks
