PLACEHOLDER Syntax for multiple Input Variables

Hi,

I am trying to pass multiple paramter values (not multi-value) it works when the first parameter is passed but does not work when I add the second parameter value. I need to pass 4 different paramters and the statement is below..

The placeholder sysntax works with hard coded values or only one PARAMETER is passed.... as below...(For clarity I aligned the placeholder syntax....

FROM "_SYS_BIC"."ZXXXXXX/ZSTAR_OT"

('PLACEHOLDER' = ('$$IP_TOMNTH$$', '201302'),

'PLACEHOLDER' = ('$$IP_FRMNTH$$', '201301'),

'PLACEHOLDER' = ('$$IP_KOSTL$$', '3001D,3004D'),

'PLACEHOLDER' = ('$$IP_BUKRS$$', '1000'))

It works as below. (when one of placeholder is provided a @Prompt as below

FROM "_SYS_BIC"."ZXXXXXX/ZSTAR_OT" ('PLACEHOLDER' = ('$$IP_TOMNTH$$', @Prompt(P_TOMNTH)), 'PLACEHOLDER' = ('$$IP_FRMNTH$$', '201301'), 'PLACEHOLDER' = ('$$IP_KOSTL$$', '3001D,3004D'), 'PLACEHOLDER' = ('$$IP_BUKRS$$', '1000')))

when I add the second parameter I get an error

FROM "_SYS_BIC"."ZXXXXXX/ZSTAR_OT" ('PLACEHOLDER' = ('$$IP_TOMNTH$$', @Prompt(P_TOMNTH)), 'PLACEHOLDER' = ('$$IP_FRMNTH$$', @Prompt(P_FRMNTH)), 'PLACEHOLDER' = ('$$IP_KOSTL$$', '3001D,3004D'), 'PLACEHOLDER' = ('$$IP_BUKRS$$', @Prompt(P_COMP_CODE)))

the error is

Substitution failed: No value supplied for Parameter "P_FRMNTH". (QTJ 00520)

Any idea why this is happening.....

Thank you,

Arthur.
