当我尝试在 Powercenter 上执行工作流程时出现以下错误

Question

Transformation Parse Warning [<<P M Parse Warning>> <<Invalid constant sun-expression>> <<Expression Error>> [TO_DATE]:invalid string for converting to Date 
… t:TO_DATE(s:s:”,s:s:’YYYYMMDD’)
……….
AND SATIS_TARIHI = >>>> TO_DATE($$RUN_DATE,’YYYYMMDD’)<<<<]; 

How can I solve this? This is the first time I encounter this error. Normally, this is a daily routine for our job. The parameter is successfully added to the mapping and all the other things seem okay. I'd appreciate your help.

I tried to start the workflow and got this error.

Answer 1

You need to define a $$RUN_DATE in mapping. Currently its not defined in mapping or its null in parameter file.

You need to set a default value in mapping like 20221221 for today.

Or else you can set it up in a parameter file like this

[folder.workflow_name]
[folder.session_name]
$$RUN_DATE=20221221

Answer 2

Considering this is your daily routine and up till now it has been working fine, I assume this is not a new development and no recent changes have been made. Apparantly PowerCenter got an invalid value for the parameter.

• Check you parameter file and how it gets generated.
• Was the process of generating paramfile executed without issues?
• Was there enough storage space?
• Can you verify the paramfile contents?
• Can you regenerate it?
• Can you modify it and provide some value manually?
