Dear Adam,
now after clarification of the term "SAP B1" =>
1.) I do have 0 experience with SAP Business One. I just checked: Getting Started - SAP Business One 9.1 - SAP Library
etc, This is a solution for small and midsize companies without any EHS capability: I was not able to find the "add on" which you have mentioned for chemcial indsutry...
Not being the exper of SAP Business One: It is quite obvious (form my Point of view) that you Need help from e.g. SAP or other Providers. If you do the set up of SAP Business One and you still have the Need to generate MSDS etc. there seems to be no other optionin place as to go on in using your existing legacy System. Now the other Topic Comes i place. if there is no "Interface" exist in this legacy System you lack of one important process step. Normally the Story is like:
based on sales order you will Need e.g. MSDS, Label etc, NOw you Need to look foroptionsusing SAP Business One to "trigger2 your legacy System to "print" something. This can be a challenge.
If you can not design an "IT Interface" you have some Kind of "double work" as you Need to Analyse data in SAP Business One and the you Need to trigger the printing inyour legay System manually.
Nobody will be happy in using this Scenario.
I can confirm that the costs for SAP ERP and EHS set up will be quite high and there is a good Chance that the management will not support this
