More specifically, the systems and methods include a sliding downhole tool with a moving screen, wherein the screen is provisionally protected by a temporary member. ## Claims ### Claim 1 A tool compromising: a screen; a temporary member that is configured to temporarily cover one side wall of the screen, wherein cement is configured to flow through an inner diameter of the tool before the temporary member is dissolved and the temporary member is dissolved after the cement flows through the inner diameter of the tool. ### Claim 2 (depends on 1) The tool of claim 1, further comprising: a seal pair that is configured to straddle the screen when the screen is in a first position, the seal pair is configured to prevent a flow across the screen. ### Claim 3 (depends on 2) The tool of claim 2, wherein in a second position the seal pair does not straddle the screen allowing the flow across the screen. ### Claim 4 (depends on 1) The tool of claim 1, further comprising: an inner sleeve configured to move relative to a fixed outer sidewall; an inner port positioned through a circumference of the inner sleeve; the screen and an inner port being offset from each other, wherein the temporary member is configured to temporarily cover portions of an inner sidewall of the screen. ### Claim 5 (depends on 4) The tool of claim 4, wherein the temporary member is configured to disappear or dissolve. ### Claim 6 (depends on 5) The tool of claim 5, wherein the temporary member is configured to dissolve after at least one of a predetermined amount of time and a heat threshold associated with the temporary member, or by mechanical methods. ### Claim 7 (depends on 1) The tool of claim 1, wherein a first portion of the temporary member is configured to be inserted into a recess, threaded, or connected above or below the screen. ### Claim 8 (depends on 7) The tool of claim 7, wherein a second portion of the temporary member is configured to extend toward a distal end of the screen. ### Claim 9 (depends on 1) The tool of claim 1, wherein temporary member is configured to allow communication between an inner diameter of the tool and a cavity housing the screen. ### Claim 10 (depends on 1) The tool of claim 1, wherein when the cement flows through the inner diameter of the tool the temporary member isntact. ### Claim 11 A method utilizing a tool compromising: temporarily covering one sidewall of a screen with a temporary member, wherein cement is flows through an inner diameter of the tool before the temporary member is dissolved and the temporary member is dissolved after the cement flows through the inner diameter of the tool. ### Claim 12 (depends on 11) The method of claim 11, further comprising: preventing a flow across the seal, via a seal pair that straddles the screen, when the screen is in a first position. ### Claim 13 (depends on 12) The method of claim 12, further comprising: allowing the flow across the screen by positioning the screen outside of the seal pair in a second position. ### Claim 14 (depends on 11) The method of claim 11, further comprising: moving an inner sleeve relative to a fixed outer sidewall; forming an inner port through a circumference of the inner sleeve; offsetting the screen and an inner frac port being offset from each other, wherein the temporary member is configured to temporarily cover portions of an inner sidewall of the screen. ### Claim 15 (depends on 14) The method of claim 14, further comprising: dissolving or removing the temporary member. ### Claim 16 (depends on 15) The method of claim 15, wherein the temporary member is configured to dissolve after at least one of a predetermined amount of time and a heat threshold associated with the temporary member, or by mechanical methods. ### Claim 17 (depends on 11) The method of claim 11, further comprising: inserting a first portion of the temporary member into a recess, threaded, or connected above or below the screen. ### Claim 18 (depends on 17) The method of claim 17, wherein a second portion of the temporary member is configured to extend toward a distal end of the screen. ### Claim 19 (depends on 11) The method of claim 11, further comprising: allowing communication, via the temporary member, between an inner diameter of the tool and a cavity housing the screen. ### Claim 20 (depends on 11) The method of claim 11, further comprising: wherein the cement flows through the inner diameter of the tool while the temporary member is intact.
