We were called upon to correct a situation. USCIS sent an RFE stating that the degree and field of study did not match with the labor certification requirements. The I-140 beneficiary had a degree in agricultural science. The employer's requirement in the labor certification was a BS degree in Computer Science, Engineering, and Mathematics.
We were hired to respond to an RFE. Client filed an EB2 I-140, where the PERM Petition required a Bachelor's and 5 years of experience. The client received an RFE in which USCIS argued the Beneficiary's degree, a Bachelor's in Commerce from India, equates to a 3-year degree and cannot be considered for an EB2 case. The Beneficiary possessed a four year Bachelor's Degree, however, this was not clearly established on his Degree. The client obtained his BS in Commerce before India switched to a standard 3-year program for his particular degree.
A beneficiary had two three-year bachelor degrees from India and consequently his I-140 petition was denied on the grounds that the beneficiary did not have a four-year bachelor's degree. We were retained after the denial. Our firm was successful in appealing and winning in less than one month. Of course, this case had unique facts. We cannot assume that all three-year degree cases will go trough this smoothly.

An I-140 petition, or Immigrant Petition for Alien Worker, is filed to petition an alien worker to become a permanent resident in the United States. The employer must file an I-140 Petition on your behalf within 180 days from the date your Labor Certification is approved by the U. S. Department of Labor. An I-140 Petition may be filed without a Labor Certification where the beneficiary qualifies under EB-1 classification.

5 November 2015: After some flip flops, USCIS has gone back to allowing carry forward of priority dates even if I-140 is revoked by employer - as described in this discussion. So, we are good for now.
In a recent meeting, Nebraska Service Center has clarified why, some times, in cases of pending I-485 applications, USCIS approves AOS interchanging the applications of the derivative and principal applicant:
Based on many posts by users of these boards, I’ve decided to write-up a fairly comprehensive posting regarding ability to pay issues and how to overcome RFE’s, Denials and appeals.
Background:
Law governing ability to pay – 8 CFR 204.5(g)(2)
USCIS recently began transferring some Form I-130, Petition for Alien Relative, cases filed by lawful permanent residents for their eligible family members from the Vermont Service Center to the California Service Center.
If your case was transferred, USCIS will send you a notice listing the transfer date and where your case will be processed. Your original receipt number will not change and this will not delay the processing of your cases except for the additional time needed to transfer the file.
