System user restriction without speacil password restriction

Hi All - is there any way to restrict a system user without speacil password restriction..

we are using control M tool to trigger job in SAP and there is a system user created in SAP for this purpose.

The control M tool is unable to trigger a job when we maintain speacil character as pasword for the system user.. It is working only when password is maintained simple.

But as per audit complicane we should only maintain speacil characters in profile paramater of SAP and just for this system use alone r we cannot change the entire sap profile parameter setting.

Please advice if something can be done to maintain simple password (password without any character and numerals) restricion just for one system user id alone.

Thanks,

Sanjeev.S
