Hello,
If you have not worked in SAP then rest of the experience is not considered towards SAP at all by employers/recruiters but it doesn't mean it is a waste. Having domain experience gives you an edge over others in understanding business requirement and finding an effective solution. Also, your work experience teaches you many things, to name a few (How to work with different stakeholders in an organization. How to work under pressure. Understand a proposed solution's impact on other things..etc).
There are companies that give opportunities to freshers also but its a matter of time that you find them or they find you, so you must constantly keep searching for jobs via job portals, LinkedIn groups and contacts, FB groups and be a regular visitor/contributor in SCN.
Don't feel low, keep brushing your skills, update resume professionally and post it on job sites.
Good Luck.
