SSIS.Pipeline Description: "component "Excel Source" (570)" failed validation and returned validation status "VS_ISBROKEN"

Back Drop

                Being a rookie at SSIS  I managed to complete my first SSIS package for a client. The package included loading data from EXCEL data and CSV  files to SQL server and subsequently loading to the datamart.

Problem

                After deploying the package at the client environment the initial runs worked seamlessly but when the larger files were tested the a validation error stated to pop out. This was utterly confusing and for few hours I dint realize what the error message said in  plain text.

Note

 The current message is last of the validation errors and there was another ballistic message that appeared before this.

The error message

What I did

-          Removed all the spaces from the file name

-       Removed the leading numeric from the excel tab name ( it later occurred to me after speaking to my friends that SQL server does not like table name to have leading numeric)
