Usecase-
We are looking at creating a reusable pipeline to load data from table1 from source DB to table1 in target DB. Plan is to reuse the same pipeline for n tables.
Option 1 -
Created master pipeline and child pipeline. Master pipeline gets table name list from source DB.
Then uses mapper and foreach snap to execute the child pipeline.
Child pipeline loads table from source DB to target DB.
Issue- Unable to use the parameter/variable value from master pipeline-foreach snap to child pipeline -snowflake select/execute snap.
Master pipeline-
Child pipeline-
Anyone faced similar error or has recommendation for the approach on reusable pipeline.
Thank You.

Hi @smahla,
You are getting that error while validating from the child pipeline because the Parameter _name is empty.
You can specify Default Values for the Parameters so you can validate, and these values will be overwritten when you invoke the Pipeline from the parent.
So, if you want to test it by validating directly the child pipeline consider setting the Default Value for the wanted Parameter under the Pipeline Properties.
Let me know if this helps. 🙂
BR,
Aleksandar.
Thanks for your input @jcornelius.
Do you have any sample pipeline with it? I am new to Snaplogic so appreciate if you could share any reference.
@bojanvelevski
Tried passing dynanic values from parent to child pipeline and it is working fine. But the child pipeline during validation shows error but runs fine when dynamic values are passed from master pipeline
Is this expected?
Please see the reference screenshots.
Child pipeline after validation-

Parameter defined in child pipeline-
Though parent and child pipeline getting completed successfully and getting the desired results but wanted to confirm if child pipeline validation errors are expected or missing something?
Thank you.
