It is difficult to answer specific questions regarding the mechanics of your organization's Standard Procurement System (SPS) as it relates to ordering ELINs. If your are using PD2 as your SPS, I would check with your PD2/SPS technical representative to see if PD2 has an option to create ELINs. If not, you would have to TO/DO match the informational IDIQ CLIN from the base contract and then establish priced SLINs under that CLIN. For clarity, I recommend you also annotate in the SLIN description what ELINs (and exhibits) these SLINs match up to. Ultimately, you should check with your organization's SPS consulting assistance, if they are available.
