Dear Michael
welcome in the world of "Substance Volume Tracking". The table CCRCC_EHS_SLIMIT does have a "special" use in SVT. Shortly:
a.) if you registered e.g. CAS 50-00-0 for pompany "Exxon" in > 100 t/a you maintained this data according to SAP EHS SVT standard model in property: "Registration (company-specific)"
b.) then you apply some general threshold limits for "warnings" etc. (50% of a value) in the customizing
Now if the substance is aggregated per company code in such a way that 50% of 100 T/a is exceeded you get a warning etc. (online checks etc.) if you have prepared a proper set up.
Now by using property "Specific Quantity Limits (SVT)" you "overwrite" these general threshold limits and system reactions. E.g. you can specify that regarding 50-00-0 you would like to get the warning not with 50% but with 40% etc.
As we are not using CCRCC_EHS_SLIMIT as you are doing it, so I can provide you only the feedback that the "trafic" light should be "calculated" by using at least the data in CCRC_EHS_REG and the "general limits" and based on the amount aggregated.. Please check if you have entries for the same specification in CCRCC_EHS_REG and check your general SVT customizing regarding the "general" warning limits (as well you should check general customzing so that CCRCC_EHS_REG would be populated properly).
So in most cases according to my experience there is no need to maintain data in "Specific Quantity Limits (SVT)" to use SVT properly
May be execute a cross read in: Substance Volume Tracking using SAP EHS MANAGEMENT; might help.

PS: may be check SAP online help as:
Data Transfer from Property Tree - Product Safety (EHS-SAF) - SAP Library

PPS: on CBRC20 you can display two types of "Status": The "Over all status" for tracked substance and the specific status for matweeriL; specification, tracked substance relation. In your screen only the overall status is shown. May be check your used layout; In most cases to have both status displayed is better
And last but not least: which SAP release do you use (indicate at least support pack and major SAP release) ? Do you use SAP Standard or did you adapted CBRc20 (you can "modifiy" if needed the "trafic" light display)? Any activation of Enhancements doen as part of "buisiness functions"?
